$2.77
Description
Discover the ultimate solution for Gran Crem espresso machines with our Espresso Portafilter O-Ring Seal—engineered to combat leaks and inconsistent brews caused by worn seals. Designed specifically for Gran Crem portafilters (#51602600), this food-grade silicone replacement ensures a tight-sealing fit between your basket and filter body, maintaining optimal pressure (9+ bars) during extraction for rich crema and balanced flavor profiles.*
Key advantages over generic O-rings:
✅ Precision fit: Tailored dimensions match original Gran Crem seals (diameter 42mm ±0.5mm).
✅ 3x longer lifespan: Silicone construction resists compression set vs standard rubber seals that degrade in under 6 months.
✅ Leak-proof guarantee: Eliminates messy grounds spills during group head insertion/removal*.
Perfect upgrade if:
• Your portafilter basket exhibits grit accumulation around edges
• Extraction time exceeds standard 25-30 seconds
• Requires frequent re-tightening after initial use
